Reaction Conditions:
with ammonium hydroxide;ammonium bicarbonate at 40; for 0.5 h;Large scale;
Steps:
6
Step C ammoniated process of the present invention is as follows: in the pot by adding 400L ammoniated concentrated aqueous ammonia and ammonium bicarbonate 15kg, stirring the prepared solution of the acid chloride was added dropwise slowly ammoniated pan, cooled with chilled brine, dropping control to control the reaction temperature below 40 , stirring was continued for 30 minutes after completion of the addition, for 1 to 2 hours, filtration, the product was sufficiently washed with cold water, drying, 3,5-dinitro - o - methyl benzamide 102.6kg, a yield of 85.9% (with respect to the nitro compounds) content of 98.5%.The present invention Buju C, set the ammonia recovery process reuse.
